Golden Rule Blog: Excessive Condensation From Air Conditioning

Why Is Excessive Condensation in My Air Conditioner a Problem?

There are three common sounds you hear from an air conditioner while it’s working: the hum of the fans, the whir of the compressor, and the drip of water moisture. The dripping water comes from the evaporator coil of the indoor unit; as warm air crosses the cold coil, water vapor condenses on the coil as it absorbs the heat. This excess moisture then drips down into a shallow pan, where a pump draws it down a drain and into the wastewater system of the plumbing.

If your air conditioning is working as it should, you won’t encounter trouble from the moisture in the system: the condensate drainage system will take care of it. But trouble can develop—algae blocking the drain, broken or loose drain line, burnt-out pump—leading to issues like water overflowing the pan or dripping out the bottom. This could even stop the AC from turning on. Should you notice water leaking from your AC, call for repair technicians right away to investigate and remedy it before you incur costs to repair water damage in your house.

Excessive Condensation From Air Conditioning

What causes excessive condensation in your air conditioning?

So what exactly is causing this excessive condensation in your air conditioning system in the first place? There are a number of factors that could help explain this phenomenon. For starters, this excess condensation could be due to bacteria found in your air conditioner that is creating a clog inside the drain. This clog causes the condensation pan to overfill, and leak water. Another contributor to this excess condensation could be the condensation pan itself, which perhaps is rusted or damaged and is causing water leaks in your homes.

Another cause of excessive condensation in your air conditioning system could be a dirty air filter. This is why regular AC maintenance and air duct cleaning is so important. Your AC's dirty air filters could be blocking the airflow over your system's evaporator coil. This causes the coil to freeze, and when it melts, it could be dripping water into the evaporation pan, leading to water leaks.

The troubles with excess condensation from air conditioning

Excessive Condensation From Air Conditioning

  • Water damage: Water pooling around your air conditioner will soon lead to extensive water damage that could cost thousands of dollars to repair if it isn’t discovered. The water damage will also start to reach other items stored around the AC.
  • Mold, mildew, and pests: Standing pools of water will raise the humidity (a comfort problem all on its own) and provide an ideal environment for mold and mildew. These growths are both destructive for building material and for indoor air quality. The water will also attract rats, cockroaches, and other pests you don’t want in your home.
  • AC shut off: As the water begins to overflow the pan, it will trigger a sensor switch designed to detect flooding. When this happens, the AC will shut off and not turn on until the situation is remedied.

Please don’t try to fiddle around with the condensate pan or the drain and pump on your own. This can lead to bigger problems should you make mistakes trying to fit the components back together, such as additional leaking. Kinks in the line could also cause a full stoppage.
